RS43 0.43″ Cantilever Mount Riser
The RS43 0.43″ Cantilever Mount Riser is designed to work with the QDS150 and QDM150 quick-detach mounts, providing additional optic height and a horizontal cantilever offset.
The RS43 raises the optic centerline by 0.43 inches, bringing the total centerline height to 1.93 inches when paired with a QDS150 or QDM150.
Its 2-inch cantilever offset provides additional flexibility when configuring compatible optics and mounting systems.
0.43″ Rise – 1.93″ Total Centerline Height
When combined with a compatible QDS150 or QDM150, the RS43 adds 0.43 inches of height, resulting in a total optic centerline height of 1.93 inches.
This raised mounting position can be useful for configurations where additional optic height is required.
2″ Cantilever Offset
The RS43 incorporates a 2-inch horizontal cantilever offset, extending the optic mounting position forward from the underlying mount.
This provides additional flexibility when positioning compatible optics within a mounting configuration.
Tested Zero Retention
The RS43 has been tested to remain within 0.25 mil after 1,000 impact cycles.
This testing provides a specified benchmark for the riser’s zero-retention performance when used as part of a compatible mounting system.
Aircraft-Grade Aluminum Construction
The RS43 is manufactured from aircraft-grade aluminum alloy and features a matte black hard-anodized finish.
The aluminum construction provides a durable mounting platform while the hard-anodized finish adds protection against everyday wear.
Recommended Configurations
The RS43 can be used in several compatible mounting configurations:
- HYDRA + QDM150 + RS43 — configured for use as a clip-on with a 1.93″ LPVO.
- NVMD + QDS150 + RS43 — raises the mounting position for a red dot at 1.93″.
- Digital Scope + QDS150 + RS43 — provides a higher mounting position for compatible digital scopes.
